Whois - An Internet utility program that obtains information (such as owner and contact info) about a Domain name or IP number from the database of a domain name registry. If the search result returns "No match", the domain name is probably available, and you can apply to register it. To search for a domain name across all registrars at once, you can use BetterWhois. WYSIWYG - An acronym for "What You See Is What You Get". A WYSIWYG program is one that allows you to create and edit a web page, text, or graphical user interface so that you can see what the end result will look like while the document is being created. WYSIWYG web page editors conceal the markup language (HTML) so as to allow the user to think entirely in terms of how the page should appear. Microsoft FrontPage and Adobe PageMill are two common WYSIWYG editors. This type of editor is usually used by the inexperienced/unskilled person who just wants to create one website, fast, without having to hire anyone. You can usually tell when someone has used such a program to create a website, because it lacks advanced functionality, may have broken or strangely sized/placed graphics, etc.
XML (Extensible Markup Language) - a specification, similar to HTML, developed by the World Wide Web Consortium (W3C) for Web documents. XML contains markup symbols (tags) to describe the contents of a page or file, but unlike HTML, the markup symbols are unlimited and self-defining (i.e. designers can create their own customized tags and tag definitions). XML is a subset of SGML (Standard Generalized Markup Language).
Zone file - A file on a nameserver that designates a domain name with all of its associated subdomains, IP addresses, and mail server. Parts of the zone file include the A record, CNAME, and MX records. A zone file is also called a "DNS table".
